HARRY PHILLIPS, OF CHICAGO, ILLINOIS.

CHAND ELIER.

SPECIFICATION forming part of Letters Patent No. 273,145, dated February 27, 18803.

Application led May To all whom it may concern Be it known that I, HARRY PHILLIPS, a subject of Great Britain, and a resident of Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in suspending Chandeliers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, in which- Figure l is a side elevation of the device for regulating the height of chandeliers as embodied in my invention. Fig. 2 is a longitudinal central section thereof upon line .fr m of' Fig. l. Fig. 3 is a horizontal section upon line y y of Fig. 2, showing the distributer, with which the burners are connected. somewhat inn detail. Fig. 4 is a detail elevation of one of the two grooved wedges or clamps which form the principal part of my automatic locking device.

Like parts are indicated b v similar letters of reference in the different figures ofthe draw- The inner or first pipe, c, extends down from the ceiling through the locking device, as shown, and all adjustments of the height ing device upon this pipe. The locking device consists of two grooved pieces or clamps, b c. These pieces are of the same shape, and are each provided with a spiral groove, d, as shown in Fig. 4. 'These clamps are placed about the pipe a., and when pressed together against the pipe there is sufficient friction between their inner concave surfaces and the convex surface of the pipe to support any required weight. The second or central pipe, e, extends below the distributer, and is connected at the upperend with the clamps b c by means of the collarsfg. The cup It is connected with the outer or third pipe, t', as shown. The spiral spring his placed under the collar f, and should be of sufficient force to support the weight of the central pipe, e, and hold the clamps b c in engagement with the screws l m, which are adjusted to the spiral grooves clin the said clamps. The central pipe, e, is provided with openings o, so that the gas may enter the distrihuter p. The

pipe e is plugged. at the lower end, and pro- 12,1812.V (N o model.)

vided with the burr or knob q. The pipe t may be provided with slots, as shown, so as to allow the knob q to move down ashort distance, carrying Awithv it the central tube or pipe, e. This independent downward motion of the pipe e must be sucient to loosen the locking device. The length of the slots in pipe i is otherwise immaterial. By pulling down on the knob q against the force of spring lt, a downward spiral motion is imparted t0 the clamps b c. Thus, by simply pulling down on the knob qi, the screws which project into the spiral grooves d are brought nearerto the upper and smaller portions of the clamps, so that the clamps are loosened sufficiently to allow them to slide upon the inner pipe or rod, a. The pipe i is screwed into the distributer, as shown at pand p, and the stuffing-box s prevents the gas from escaping between the pipes t' and c. The stuffing-box r comes next to the gas or stationary pipe a, and prevents the gas from escaping between said stationary pipe and the pipe e. The chandelier may thus be raised and lowered, as desired.

My locking device may be used with lamps or candle-chandeliers. In this case I dispense with the packing r s, and may use a rod instead of the pipe a.

k, My locking device works best when the clamps are grooved and used in combination with the screws L m. I find, however, that good results may be obtained by usingclamps that are not provided with the spiral grooves, and dispensing entirely with the screws or projections l m. This may be demonstrated by simply removing the screws l m and using the device as hereinbetore described. When used without the screws lm, the outer surfaces of the wedges comeagainst the inner surface of the cup h,and thus sufcient friction is produced to hold the chandelier at any desired height.

I claim- 1. The combination, substantiallyas hereinbefore Aset forth, of the spirally grooved wed ges, with the adjustable projections, a spring for forcing the wedges against said projections, and means whereby 'a spiral motion' may be imparted to the wedges, so as to bring the projectionstoward the smaller ends of the IOO 2 erwies 1o lche purpose specified.

3. The locking device consisting of the clamps or Wedges, in combination with the cup L, the spring 7c, and pipe e, whereby sufficient friction may be produced to hold the chandelier, Substantially as set forth.
